CHAIN ATTACHMENT FOR SASH-BALANCES.

SPEGIFIOATION forming part of Letters Patent No. 398,221, dated February 19, 1889.

Application filed February 25, 1888. Serial No. 265,287. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD A. BREUL, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Chain-Connections; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates more especially to the class of connect-ions used in attaching chains to weights and sashes, but is of course applicable to all other classes of fixtures in which chains are used, and has for its object to improve and at the same time to cheapen the construction of the connections. These results I accomplish in the simple and novel manner which I will now describe, referring by numbers to the accompanying drawings, forming part of this specification, in which Figure l is a section of a sash, jamb, pulley-case, and pulley, the connection by which the chain secured to the sash being in section, and a chain, weight, and weight-hook in elevation; Fig. 2, a view of the chain and connections detached, the weight-hook being shown in edge view and the sash-connection in rear elevation; and Figs. 3 and i are views of the parts of the sash-connection detached.

1 denotes the sash; 2, the jamb; 3, the chain; l, the pulley; 5, the case, ando the weight. These parts, as shown, are of ordinary construction. The style of chain used is not essential to the operativeness of lily-invention, my present connections being equally adapted for use in connection with either wire or sheetmetal chains. 1

7 denotes the groove in the sash in which the chain runs, and 8 a recess below the groove, which is adapted to receive a cup or thimble, 9, and a pin, 10, by which the chain is connected to the sash. The cup or thimble is provided with .a slot, 11, in one side, the upper side in use, and an opening, 12, at the back. The pin is ordinarily provided with a reduced portion, 13, about midway its length, and is preferably beveled at one end, as at 14, for convenience in use.

The parts are connected as follows: The loop of the end link of the chain is passed through opening 12 in the cup or thimble, which draws the second link into slot 11. The pin is then forced through the loop of the link until. the loop rests in reduced portion 13, as clearly shown in Fig. 2. The slot and openingare so proportioned in use that the pin has to be driven with some force to seat it in position. This wedges the second link tightly in slot 11, so that the pin and the end and second links are made perfectly rigid with the cup or thimble and cannot move in the slightest in use. The thimble is then seated in recess 8, fitting loosely therein, so that it may be readily removed at any time when it is required to connect or disconnect the chain for repairs or other purposes. 15 denotes a metallic loop by which the opposite end of the chain is connected to the weight. This loop maybe made of a round or ilat wire, and is provided with hooks 16 at both ends, which lie parallel to each other and side by side. The opening at the upper end of the weight is made large enough so that either of the hooks maybe readily passed through it, the weight being supported in use by the center of the loop.

The peculiarity of construction of my improved loop is that the end of each hook is curved inward toward the back thereof far enough to pass the end of the other hook, as is clearly shown in Fig. 1, thus forming a perfectly-closed eye, 17, in which the last link of the chain lies. I thus insure that in use, no matter how severe the shocks may be upon the loop, resulting from various movements of sash or weights, it shall be impossible to dislodge the lastlink of the chain from the eye. This is an important feature, as it wholly obviates what has heretofore been a serious objection to this class of fixtures Having thus described my invention, I claim 1. The combination, with a sash-chain, of a cup or thimble having an opening at the back, through which the loop of the last link passes, and a slot at the top, which receives the loop of the second link, and a pin passed between the loop of the last link and the back of the cup 01' thimble, whereby the chain en li inward past each other, so that an eye, 17, is i0 is helcl Without 10st motion. 1 formed, which incloses the chain in use and 2.
